CLAMP FOR FRUIT-JARS.

To all whom it may concern:

Be it known that I, LOUIS HONSTEIN, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented a new and useful Clamp for Fruit-Jars, of which thefollowing is a specification.

This invention relates to clamps for holding fruit jars, on a table, orother sup ort, while thecap is being screwed onto, or 0 of a ar.

In preserving fruit in glass jars, there is great trouble and difficultyin screwing the cap upon the jar, as the contents render the jarextremely hot, makin it difficult to handle the ar, while the cap isscrewed on tight. Also, in unscrewing the cap, the 'ar must be heldfirmly to unscrew the cap, W ich is done with difliculty, as the capbecomes wedged in ace.

p The object of this invention is to provide an im roved clamp forholdin a fruit jar to a tab e, by means of which t e jar will be firmlyheld in place, and prevented from becoming loose, and working off of thetable, and by means of which also, the jar may be readily clamped inplace and held from turning.

The invention consists of an improved fruit jar clamp, constructed, ashereinafter set forth and claimed: 7

Referring to the drawing, Figure 1 is aperspective view of a fruit jarclamp constructed in accordance with this invention, and shown assecured to the ed e of a table. Fig. 2 is a side view thereof. Flg. 3 isa erspective view of the movable jaw detac ed.

The clamp consists of a circular plate 1 of iron, or wood, or othersuitable material, and formed at one side with a fixed curved jaw 2,adapted to fit against the side of a glass fruit jar. At the oppositeside from the fixed jaw, the late 1 is formed with an extension 3,provid ed with parallel slots 4,'each open at its outer end, and eachcommunicating at its inner end with an opening 5 in the plate 1. An arm6 extends between said openings 5, and projects beyond the extension 3,terminating in an upturned end, or bracket 7, the arm 6 forming with theextension 3 the slots 4. Resting on the extension 3 is a curved slidablejaw 8, having on its lower edge the inclined lugs 9, which projectthrough the slots 4, and embrace the inclined sides 10 of the arm 6, thelugs 9 serving as guides to steady-the jaw 8 in its movement.

Specification of Letters Patent. Application filed May 6, 1908. SerialNo. 431,269.

Patented Oct. 20, 1908.

Thejaws 2 and 8 each have their inner clamping surface preferablyprovided with a strip of rubber 11, secured thereto by glue, orotherwise, the rubber surface preventing injury to the glass jar, andholding it from slipping. The jaw 8 may be operated by any suitablemeans, and, as here shown, referably by a screw shaft 12 having a cranhandle 13. The screw shaft 12 extends through and engages ascrew-threaded hole 14 in the bracket 7, and has its forward endunthreaded and projecting into a hole in the slidable jaw 8, andconnected to the jaw 8 in any suitable manner to turn freely thereon.

In order to firmly secure the clamp to a table, or other suitablesupport, the plate 1 is provided on its under side with an L- shapedbracket 15, having a clamping screw 16 extending through the bracket 15,with a clamping head 17, pivoted on its outer end. To steady the plate 1against lateral movement, when it is clamped to a table, it is providedon its under side, at a suitable distance from the bracket 15, with twolugs or projec tions 18, adapted to bear against the edge of a table.

When the clamp is attached to the edge of a table, the plate 1 rests onthe table, as shown, and the bracket 15 and lugs 18, bear against theedge 19 of the table. The clamping screw 16, bearing tightly against theunder side of the table serves to hold the clamp firmly thereon, thelugs 18 at a spaced distance from the bracket 15, on either side thereofholding the clamp from moving laterally when force is applied to screwon a cap, or unscrew it from a ar. A glass jar 20, as shown in dottedlines in Fig. 1, having been placed on the plate 1, with one side of itslower end abutting against the fixed jaw 2, the slidable jaw 8 isadvanced against the opposite side of the jar by operating the screw 12,and is brought to bear firmly against it, thereby securely holding thejaw in clamped position. The clamp is adapted to hold jars of differentsizes, and a jar may be easily and quickly clamped thereon by a singleturn of the screw 12; A ar being firmly and rigidly clamped on a table,as herein set forth, a cap can be conveniently and readily screwed on oroff of the jar.

What is claimed is 2-- 1. A fruit jar holder comprising a base memberhavin a fixed jaw and provided with an integra clam ing bracket, aclamping member carried y said bracket, that portion of the baseopposite the fixed aw bel ing arranged to form a guiding bar, a slidablejaw mounted on the guiding bar and means for operating the slidable aw.

2. A fruit jar holder, consisting of a base having a fixed jaw on oneside, and a guide bar, and guide slots on its opposite side, a slidableaw having guide lugs engaging said guide bar, means for operating theslidable jaw, and means for clamping the holder to a support.

3. A fruit jar holder, consisting of a base having a fixed jaw on oneside, and a slotted projection, and guide arm with tapering sides andbracket on its opposite side, a slidable jaw with tapering lugs engagingthe slots in the projection and the guide arm, an operating screw shaftmounted in the bracket of the guide arm, and connected to the slidablejaw, a bracket with clamping screw depending from the base, and steadyinlugs on the base on opposite side from the lamping bracket.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
